IMPROVEMENT IN COMBINED BROADCAST-SEEDERS AND CULTIVATORS.

Specification forming part of Letters Patent IWL-110,447, dated December27, 1870; antedated December 10, 1870.

To whom it may concern:

Be it known that I, JOSEPH E. FARGO, ot' Lake Mills, in the county ofJefferson and State of Wisconsin, have invented a new and usefulImprovement in Combined Broadcast- Seeder and Cultivat-or; and I dodeclare that the following is a true and accurate description thereof,reference bein g had to the accompanying drawing, and to the letters ofreference marked thereon, and being a part of this specification, inwhich- Figure 1 is an elevation of my improved machine. Fig. 2 is a planof the same with the hopper removed. Fig. 3 is a vertical section of thefeed-box, and Fig. et is a horizontal section of the same. j

Like letters indicate like parts in each ligure.

The nature of this invention relates to an improved construction ofcombined broadcast seed-sewers and cultivators; a-nd consists in thepeculiar arrangement of recessed cylinders rotating in feed-boxessnrmounting the axle, for automatically delivering a regulated amount ofseed to the spout-s, which have distributing-plates at their lower ends,whence it falls to the ground, and is covered by the cultivator-teethattached to bars pivoted to a shaft in rear of the axle 5 the feedmechanism is operated by gearing from the tractionwheels; in thepeculiar method of hanging the drag-bars, and the arrangement of themechanism for raising and lowering the same also, the peculiarconstruction of the washers between the drag-bars.

In the drawing, A represents tractionwheels, and B a proper axle,mounted in and between them. One of the wheels has secured to its hub aspur-gear, a., which meshes with and rotates the pinion b, which has ahalfclutch, b', on its outer face, and rotates loosely on the sleeve c,which forms an extension or prolongation of the feed-shaft O, with whichit engages and transmits its motion by a pin through the shaft,projecting into slots in the sleeve. 0n the outer end of the sleeve apin is thrown in or out of gear with the half-clutch b by the lateralmovement of the sleeve, which is effected by a shifter, D, Fig. 2. Theclutch b is so constructed thatfu-'hen'thrown in gear with the pin onthe end of the sleeve, the latter, together with the shaft C, will notbe rotated in the retrograde movement of the machine, a spring beingcoiled around the sleeve,

between its journal and shifter-collar, which allows it sufficientend-play for the purpose.

The shaft O and its sleeve rotate in bearings into the feed-boxes H, butone of which is shown.

I is acylinder, recessed with several grooves or corrugations, extendingfrom one end to about midway of its length. This cylinder is secured tothe feed-shaft C, and rotates within the feed-box H, its plain endserving as a journal.

The'grain or seed dropping into the feedbox from the hopper in therotation of the cylinder, the grooves ll with seed, which they carrydown until they reach an opening in the bottom of the feed-box, when theseed passes down and out of the spout J, when it falls on adistributing-plate, j, which is formed by turning back horizontally theelongated lip of the spout. Froln the plate j the seed falls broadcaston the ground.

In order that the seed may not run out at the side of the feed-boxthrough the recesses in the cylinder, a washer fitting into saidrecesses is slipped over the cylinder and rotates with it, bein gheldagainst the face of the feedbox by clamps or other proper means.

In the back part of the feed-box is hung a vibrating guard, K, which ispressed forward toward the cylinder by means of a rubber or otherspring, lc. The. face of the guard conforming to the outline of thecylinder forms the back of the feed-box. The purpose I have in the useof the vibrating guard is, that in case the seed or grain should becaught -in the rotation of the cylinder by the sharp corner of one ofits recesses, it willnotbe crushed against the throat of the back-ot'the feed-box, were it stationary; but the spring 7c will allow the guardto recede a little and permit the seed to pass down.

'lo increase or diminish the discharge of seed, the shaft C is movedlaterally by the shifter F, so as to bring more or less of the recessedportion ofthe cylinder within the feed-box.

L are drag-bars, journaled on a bar secured to the frame-standard in therear of the axle, cach bar having a cultivator-tooth, M, attachedunderneath. The teeth are attached to the series of bars in a zigzagrow.

The bars are separated from each other by hemispherical Washers Z, caston a plate, which is screwed or otherwise secured to the side of thebar. This form of washer gives a longer bearing to the bar and lessensthe tendency of the tooth t0 twist in its furrow.

N is a rock-shaft, pivoted or journaled eeeentrically in the anteriorpart of the i`ra1nestandard, and has secured to it a series of chains,O, one of which is secured to each of the drag-bars below.

P is a lever, secured to the rock-sh aft within reach of the driver, whosits on the hopper, and by which he rotates said shaft to raise or lowerthe shovels or cultivator-teeth.

Q is a notched quadrant, secured to the lever and rockshaft, which isheld in any desired position by the dog It, pivoted to the axle, whichhas a stud projecting from one side, which engages with one of thenotches in the quadrant.

To release the dog from the quadrant, a bellcrank lever, p, is pivotedto the gripe of the lever P, and by means of a wire, p', connecting itwith a tripper, q, under the dog, the latter is raised out of the notch.

As the operation of this machine is so clearly shown in the drawing andby the foregoing description, a further explanation is deemedunnecessary.

What I claim as my invention, and desire to secure by Letters Patent, is

l. The feed-shaft C and sleeve c, shifter D, clutch b', pinion b, andgear a, arranged and operating as and for the purpose set forth.

2. The partially tinted or recessed cylinders I, secured t0 the shaft Cand rotating in the feed-box H, vibrating guard K, spring lr, spout J,plate j, and shifter F, substantially as dcscribed, and operating forthe purposes herein set forth.

3. The rock-shaft N, eccentrically journalcd in the frame-standards E,and operated by means of the lever P, notched quadrant Q, dog It,bell-crank lever 19, wire p, and tripper q, for raising the dragbars Lby means ofthe chains O, substantially as described.

4. The hemispherical washers l, in connection with the drag-bars L, whenconstructed and arranged as described and shown, and as and for thepurpose set forth.
